You're right any dog can be vicious. Chihuahuas can sometimes even break the skin. Toy poodles attacks have been known to result in Bandaid use.

I’ve come across many specimens of the oh-so-dangerous breeds, and they have all been sweethearts.

The only dog that ever snapped at me-—bit me, actually-—was a small yapper.

We have one of those little yappers. Best burglar alarm there is. Damned thing has taught the bird to bark too. You get both of them going at the same time, and you can't hear yourself think.
